Jade paid $33 for renting a pair of rollerblades starting from 15 00. What would be the latest time she must return the pair of rollerblades to the shop?
Amount that Jade paid for all the additional
12 hours
= 33 - 8.50
= $24.50
Number of sets of additional
12 hours
= 24.50 ÷ 3.50
= 7
Total additional time that Jade paid for
= 7 x
12= 3
12 h
Total time that Jade paid for
= 1 + 3
12= 4
12 h

12 h after 15 00 = 19 30
Latest time that Jade must return the pair of rollerblades to the shop: 19 30
Answer(s): 19 30
